Just when I thought I had my subject figured out, I came across another researcher whose work has shaken my perspective on several points I thought were settled. Shaken, but not destroyed; rather, Michael Levin’s insights cast light into some of the murkier corners, and offer support where support was needed. Since I am presently twelve chapters in to a book on personal identity and the human experience of self, it is unsettling to realize that I will need to go back and revise biggish parts of it—but it is reassuring that these changes point in the direction of a stronger theoretical foundation for conclusions I had already reached.

Levin is a thinker who makes my head explode. He offers a fundamental paradigm shift in thinking about the units of life. The defining principle of a living entity is its orientation to the homeostatic goal of maintaining its own living conditions: self-regulating  its temperature, its oxygenation, its nutrition, its safety, etc., within the range optimal for growth and reproduction. Significant deviations from these homeostatic norms are stressors; the entity seeks to reduce stress.

After a Long Absence

Here I am again.

I say “I” hesitantly, given the context. Anyway, this self-same bundle of attributes, having lost and gained more than a few (attributes) over the years, persists with enough continuity to be recognized as the same person.

I did not die of melanoma. With the help of state-of-the-art immunotherapy, my immune system made short work of the cancer. But my ramped-up, unleashed immune system also destroyed my thyroid, and my thyroxine levels fell to levels that are clinically rare. Thyroxine controls the body’s metabolic rate, and therefore everything. I was treated for hypothyroidism, but not before falling into a deep depression, which left me unable to write, or think, or even compose a simple email without revising it for hours.  Here is a fragment of writing from that time I found this morning in an old file:

Yesterday I thought I could perhaps write again, another blog post. But the attempt seems to have cast me into the pit of despair. I wanted to do something simple and clear, something I could be proud of.

Anyway, that explains my absence. The road to recovery was long, involving physically-demanding tasks far removed from the philosophy of personal identity.  This past summer, I finally began to think about taking up this project again. Then I got an email out of the blue (or whatever colour cyberspace is).  It started out

Hi Gordon,
I want to thank you for so clearly and plainly
explaining this idea of self-concern in your
illusion of survival post. Before I found it
I had been searching for a way to positively
conceptualize the possibility that Parfit's
extreme claim was real. I've now read that post
many times and a number of your other posts from
the blog. I've shared the illusion of survival
post with many of my friends but it seems it
doesn't fascinate them as it does me.

That hooked me. I have friends like that too. The email was from Scott  Emerson.  Scott said he wanted to “somehow make the illusion of survival post into a video for people who aren’t interested enough to read very much.” We started corresponding, met on Zoom. Scott’s video went through several drafts. This week he published it on YouTube.

It’s interesting and rewarding to see someone else’s sympathetic take on ideas you have worked with a long time.  Scott’s lens is not my lens; he says things I wouldn’t say, and says things I would say in ways I wouldn’t think of saying them. That is to be expected. We are different people, with different backgrounds. Variation adds depth to the topic, and broadens its appeal. Scott’s video grew from seeds planted by Parfit, by William Hazlitt, by Nagarjuna, seeds of the same lineage that sprouted as the Phantom Self  blog. The existence of Scott’s video proves that the seeds remain viable; this is a life form that can survive and thrive in the competition of ideas. I invite you to watch it. It is also in text form here. As always, both Scott and I welcome your comments.

Questioning Capgras

CapgrasSomeone with the Capgras delusion has the stubbornly ingrained belief that a person or persons close to her—her spouse, her parents, her child—is someone else, a stranger, an imposter.

Although rare, Capgras is of interest because understanding it could shed light on the normal processes by which people recognize people. To decide that you are in the presence of your wife, not a stranger who bears an uncanny resemblance to your wife, is to make a personal identity judgement. We make them all the time, usually automatically and effortlessly with people we know well, sometimes with effort when we struggle to place a familiar face encountered in an unusual setting. An understanding of how beliefs about personal identity can go so spectacularly wrong in Capgras and related disorders may afford insight into the ordinary intuitions we rely on to recognize other people and ourselves.

Tick…tick…tick—a reply to Ian Brown

Ship's clock(small)I like Ian Brown’s birthday pieces—about turning 55 in 2009, now 60 in Feb 8th’s Globe and Mail—because they so eloquently express the feelings that come naturally to people on their birthdays, starting around age 30: the sense of time running out, the vision of one’s remaining life as a diminishing resource, the fear that its quality will deteriorate.  He writes:

I began my 60th birthday underslept, with a brewing chest infection, and…not at all pleased to have reached the milestone—standing as I was on the threshold of the no-man’s land beyond sixty. Sixty! I mean, Jesus wept: How did I get to be this old? Continue reading “Tick…tick…tick—a reply to Ian Brown”

Amputation Desire (BIID/Xenomelia) and the Human Experience of Self

Amputation desire 0222To say that amputees have phantom limbs and whole-bodied people do not is misleading. The so-called ‘phantom’ is the brain’s representation of the body, something everybody has. As neurologist Ronald Melzack put it, “the phantom represents our normal experience of the body.” [Melzack, 1989, p 4]

Amputees differ from other people in that they notice their phantom limbs, while the rest of us do not. They notice them because the corresponding limb of flesh and blood is missing. The difference between representation and reality is what makes the amputee’s phantom salient. The rest of us fail to notice our body phantoms because, when all is well, we cannot distinguish them from our bodies themselves.

I have started to think of the phantom as ‘the brain’s user interface to the body.’ It’s  a very good interface, one that might have been designed by a genius like Steve Jobs. It gives your brain exquisite control over your body while remaining utterly transparent to you, the user. Most people go through life without ever realizing that the interface exists.

The interface is so transparent, it only becomes visible at all when there are discrepancies between representation and  reality. In this blog, I’ve taken brief looks at two kinds of discrepancy: the phantom limbs which almost all amputees experience, and the rubber-hand illusion which allows an ordinary person to observe her phantom from a new perspective by tricking her brain into shifting the phantom from her real hand to an obviously fake, dummy hand.

The Human Kludge

Human Kludge (glowing edges)Natural selection—Richard Dawkins’ ‘blind watchmaker’—has come up with some remarkable designs over four billion years. Those that persisted are, to a greater or lesser extent, effective responses to evolutionary pressures. But many of these design solutions are far from optimal. Natural selection is an opportunist, whose default move is to recombine existing resources, cobbling something together from bits of earlier work rather than redesign from the ground up.

When I worked in software development, it was our default move too. Most programmers don’t mind describing themselves as “lazy.” Reinventing the wheel is rarely the best solution, if you have a library of previously developed, de bugged, tested implementations of rims, axles, and drive trains that have seen a few years of revenue service. Programmers like to re-use their old code because they know it works. Also, it’s usually the fastest way to meet a deadline. “Lazy” can be efficient and smart.

Although they may perform reliably, solutions assembled out of a hodgepodge of old components rarely look as nice as if someone had time to sit down and design them from scratch. And because the components were not originally made to work together , there is a greater risk of unintended side effects.

The Free On-line Dictionary defines a “kludge” (pronounced “klooj”) as:

1. A system, especially a computer system, that is constituted of poorly matched elements or of elements originally intended for other applications.

2. A clumsy or inelegant solution to a problem.

Close scrutiny of the human motivational system reveals a kludgy design. A uniquely human, state-of-the-art module for visualizing and planning the future was bolted on to the emotional apparatus of an iguana. The result works, but not well. On the whole it has been hugely adaptive, allowing us humans to flourish, multiply, and dominate our planet, outcompeting all other large species. But it is far from optimal, often working against itself, driving behaviour that is not at all adaptive either for the individuals involved or for our species as a whole. Moreover, it has unpleasant side effects.

In this post I will outline a theory of this design: how it came to be, its primary components, and why it works as well as it does. I will also lay out some of its shortcomings, and recommend an alternative, improved solution. Continue reading “The Human Kludge”

Where Did You Say We’re Going?

Earthrise (150)This may seem off-topic, but it’s not. I heard a talk last night by Bill Rees, who originated the concept of the ecological footprint. He presented many slides showing that we are on an unsustainable path. Of course, that isn’t news. We’ve known for a long time that we’re on that path. Bill’s slides were just a progress update—a few more data points representing a few more years since Al Gore showed us we were on that path. We have stayed right on track.

One striking slide showed the path as it was foreseen by the Club of Rome in its Limits to Growth report. The authors created a computer model showing trends on several measures including world population growth, industrial output, pollution, food production, and resource depletion. Trends were plotted assuming several scenarios reflecting different levels of intervention. The scenarios ranged from business-as-usual to sustainable. The business-as-usual trends, based on available historical data, showed a remarkably consistent pattern. The trend lines passed the planet’s carrying capacity in the 1980’s, moving into what is called “overshoot.” Overshoot is growth beyond carrying capacity—a condition which, if not corrected, leads to collapse.

The Illusion of Survival

TheIllusion of Survival (small)When people ask what the Phantom Self is about and I have to come up with an elevator speech of a minute or less, I’ve started saying something along the lines of, “There is no fundamental difference between your relationship to your future self and your relationships to other people.” This sometimes strikes a chord, making people want to hear more. It’s better than leading with teleportation, although teleportation is not bad at parties, where people take it as an invitation to play; they light up and start recalling the Hollywood fantasies they enjoyed in their misspent youth, the more outrageous the better. It’s way better than starting off with the idea that we are informational entities, to which people respond as though they’d stepped in something squishy.

There’s no doubt that this material is hard to understand, still harder to explain. It doesn’t help that it’s spread over 60-odd posts written over three and a half years. I can’t distill it all into a one-minute elevator speech. But if I had to pick one key finding—the most important—it would be that personal survival is an illusion. And although support for this claim—which is puzzling and incomprehensible if you come across it cold—is scattered throughout 400 pages or so, no single post addresses this point directly.

So here goes. Continue reading “The Illusion of Survival”

Uploading Ray Kurzweil

In The Singularity is Near, inventor and futurist Ray Kurzweil argues that the rate of technological progress, which is exponential, will reach a critical point about 2045 when its impact will be “so deep, that human life will be irreversibly transformed.”  Before then, he predicts, human beings will have uploaded themselves to vastly more intelligent and robust machines. Kurzweil—who was born in 1948, as I was—expects to make that journey personally. Continue reading “Uploading Ray Kurzweil”

Leary on the Curse of the Self

Mark Leary begins The Curse of the Self by imagining himself giving a commencement address in which he tells the graduates that in their lives ahead, “The primary cause of your unhappiness will be you.” People make themselves unhappy “because of how the human mind is designed.” That design includes an ability to self-reflect which allows us “to plan ahead, reminisce about the past, consider options, innovate, and evaluate ourselves.” But it also “distorts people’s perceptions of the world…prompting them to make bad decisions based on faulty information.” [Leary,2004, p.vi]

Leary’s book is about the self-inflicted suffering and delusions which arise from how human view themselves—a subject familiar to any Buddhist. Although Leary’s views emerge from contemporary Western psychology, Leary is aware of their convergence with those of the Buddha, who had what Leary describes as “a surprisingly modern view of  the self.”  Continue reading “Leary on the Curse of the Self”
